以上接口均包含PHP、Python、C#和Java等四种语言的代码示例,以 获取电视台分类 API为例:
(1)基于PHP的 获取电视台分类 API服务请求的代码示例
<?php
$method = "POST";
$url = "https://api.apishop.net/common/tv/queryCategory";
$headers = NULL;
$params = array(
);
$result = apishop_curl($method, $url, $headers, $params);
If ($result) {
$body = json_decode($result["body"], TRUE);
$status_code = $body["statusCode"];
If ($status_code == "000000") {
//状态码为000000, 说明请求成功
echo "请求成功:" . $result["body"];
} else {
//状态码非000000, 说明请求失败
echo "请求失败:" . $result["body"];
}
} else {
//返回内容异常,发送请求失败,以下可根据业务逻辑自行修改
echo "发送请求失败";
}
